22:28:10,233 DEBUG org.apache.hadoop.hbase.util.ByteStringer
- Failed to classload HBaseZeroCopyByteString:
java.lang.IllegalAccessError: class com.google.protobuf.HBaseZeroCopyByteString
cannot access its superclass com.google.protobuf.LiteralByteString
Can you check the classpath ?
HBaseZeroCopyByteString is in hbase-protocol module.
Were you running against hadoop-1 or hadoop-2 ?
Cheers
